A fishing boat approaches a caution buoy 100 m ahead at a velocity of 31.0 m/s. The pilot reduces the throttle, slowing the boat with a constant acceleration of −3.20 m/s2. (a) How long (in s) does it take the boat to reach the buoy?  Answer:__________s (b) What is the velocity (in m/s) of the boat when it reaches the buoy? (Indicate the direction with the sign of your answer.) Answer:__________ m/s
